## Discrepancy

AFTER SEPARTURE AT ABOUT 3000 FT MSO AMBER MASTER CAUTION LIGHT ILLUMINATED, MOMENTARILY.  ALSO, ELECT LOOK UP LIGHT ON, BOTH WENT OUT AFTER 2 TO 3 SECONDS.  REPEATED EVERY 3 TO 4 SECONDS FOR THE NEXT 1=30 UNTIL LANDING, CEASED ON TOUCH DOWN.  THEN CHECKING STANDBY GEN SHOWED ABOUT 25V IN OFF POSITION, CYCLED ON/OFF AND VOLTAGE FINALLY ZEROED.  NO OVERHEAD ELECT LIGHT ON.  MAINTENANCE COULD NOT DUPLICATE, OPERATED IN GROUND/AIR MODE, NO DEFECTS AT THIS TIME.  REPLACED PCB WQ5.  OPS CHECK GOOD AT THIS TIME.
